Aligned For Successful Application
As standard, the dry thermoplastic TecWeb® is delivered on a roll without foil or silicone paper. On customer request, delivery on a carrier is possible. TecWeb® adhesive is not a film with a closed surface, but a porous three dimensional structure. The open structure makes the resultant laminate more flexible and breathable. Due to the structure of TecWeb® adhesives, other names such as veil, non-woven, nets or fleece adhesive are common.
Flexible And Innovative
TecWeb® offers an extremely versatile pallet of High-Tech adhesives. This large flexibility results from different base polymers used to formulate the webs, e.g. co-polyamides, co-polyesters, co-polyolefins and co-polyurethanes. Webs are available in weights from 6 g to 60 g per square meter and in wide widths.
Temperature, Pressure And Time
In order to process TecWeb®, three fundamental parameters are to be considered: temperature, pressure and time. To activate the thermoplastic web adhesive, a glue line temperature above the melting point is required. Pressure and time are then coordinated with the respective substrates, in order to ensure the highest quality laminate.
